it'll get louder
If both dimensions are doubled then the area is quadrupled. This is true of any geometric shape.
the surface area quadruples.
The Value of the Mean will Double as well.
IF a wave moving at a constant speed were to have it's wavelength doubled (Wavelength x 2), then the frequency of the wave would be half of what it originally was (Frequency / 2).
The volume would increase by a factor of 23 = 8
The resulting waveform will have the same frequency as both components although the amplitude will be doubled.
Amplitude - video game - happened in 2003.
Then the signal will be the same amplitude.
It gets wet.
Momentum = mass x velocity. So if the velocity is doubled, momentum will be doubled as they are directly proportional to each other.
It gets louder or quieter.
If both dimensions are doubled then the area is quadrupled. This is true of any geometric shape.
If the potential difference between the ends of any conductor is doubled, then the current through the conductor is also doubled.
That will not happen unless matter is undergoing a phase change and the temperature you are measuring is that of the matter undergoing the phase change.
increases by 6 dB
The acceleration will be doubled accordingly. From 10m/s2 to 20.
Intensity of sound is dealt as volume in case of radio sets. Intensity is directly proportional to the square of amplitude. So as volume is turned down, intensity is reduced and so the amplitude is decreased.
